金属的腐蚀和防护是世界性的科技难题,仅钢铁每年因腐蚀造成的损耗量,全世界高达2.3亿t.我国每年因金属腐蚀造成的经济损失也在450亿元以上.为解决这个世界性的科技难题,满足我国各行各业的现实需要,中国矿业大学大正表面新技术公司针对国内钢构件长效防腐的迫切需要和国内电弧喷涂技术落后的实际情况,开展了钢构件电弧冶金喷涂的技术攻关,经过反复试验,终获成功,并筛选出了最佳工艺参数.
Metal corrosion and protection is a worldwide scientific and technological problems, only the annual loss of steel caused by corrosion, the world up to 230 million t.China’s annual economic losses due to metal corrosion is also 450 billion yuan or more. To solve this worldwide Technology challenges to meet the practical needs of all walks of life in our country, China University of Mining and Technology Corporation is a new surface technology companies in response to the urgent need for long-term preservation of domestic steel components and the domestic arc spraying technology behind the actual situation, carried out the arc welding of steel components metallurgical technology Research, after repeated tests, eventually succeeded, and screened the best process parameters.
